Comment 2 for bug 801242

> I would close this as it is described now because users should never be permitted to request to join a restricted team, which is the case of the private team.

But this is just restating the current behaviour, not an argument for keeping that behaviour.

I think there is a real problem here that has occurred several times. People get the link and then can't do anything useful with it.

There are various solutions, some of which overlap with other bugs:
 * show people "this object exists but you're not allowed to see it", if they guess the right url
 * have an organization model so people in ~canonical can see ~canonical-foo and freely choose to join it

Adding an 'invitation to team' feature wouldn't have specifically solved my case because I sent the invitation to a large team.
